Cylindrical packing factor
WebInitially, packing models are classified into ordered (reg-ular) [2,24], and disordered (random) packings [3,6,22,25-29]. Ordered packing arrangements comprise rows and lay-ers placed in cubic or hexagonal crystalline patterns. A ran-dom packing with highest density is referred to as a random close packing. The term random indicates that the pack- WebThese are grain size, grain packing, particle shape, and the distribution of grain sizes. However, the initial porosity is rarely that found in real rocks, as these have subsequently been affected by secondary controls on porosity such as compaction and geochemical diagenetic processes. This section briefly reviews these controls. 5.2.1 Grain Size
